INK-PAD.

Specification of Letters Patent.

Patented April 2, 1907.

' Application filed May 11,1906. Serial No. 316,251.

To (LZZ whom, it may concern;

Be it known that I, ALFRED B. CHANDLER, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ink-Pads, of which the following is a full, clear, and exact specification.

This invention relates to improvements in ink-pads which comprises a suitable box or other receptacle in which is permanently secured a pad prepared of felt or other suitable material adapted to absorb and supply ink to a rubber or other stamp pressed thereon and in suliicient quantities to make the desired impression from the stamp.

The prior structures above referred to are objectionable for two reasons, one being that when frequently used and with great rapidity of stroke of the stamp the surface of the pad so soon becomes frayed and worn out that an objectionable expense attends its use, the other reason being that when not frequently used and before any substantial use is made of it the ink saturating the pad cakes and hardens the surface, with the result that the pad will not successfully deliver its ink to the stamp and is injurious to the stamp, and must, therefore,be thrown away, although otherwise it is in a good state of preservation.

The object of my invention is to provide an ink-pad structure the pad of which may be conveniently and quickly removed from its receptacle and a new pad substituted therefor with quick facility and convenience.

A further object is an ink-pad structure the ink-p ad of which is not only quickly and conveniently removable from, but as quickly and conveniently reversible in its receptacle.

A still further object is an ink-pad structure having a removable and reversible pad, the opposing surfaces of which are isolated from each other by non-absorbent material and a material which may be utilized for binding together the edges of the absorbent material and also for detachably securing the pad in its receptacle and against accidental detachment therefrom.

With these ends in view my invention consists in certain features of novelty in the construction, combination, and arrangement of parts, by which the said objects and certain other objects hereinafter appearing are attained, all as fully described with reference from one side thereof, (see Fig. 3,)

to the accompanying drawings, and more particularly pointed out in the claims.

In the said drawings, Figure 1 illustrates a perspective view of an ink-pad embodying my invention, and particularly the means providing for the removal of. the ink-pad proper from its receptacle at one side thereof and retaining the pad against accidental detachment, while at the same time a receptacle is provided which may be closed when the pad is not in use; Fig. 2, an enlarged central longitudinal section on the line 2 2 of Fig. 1; Fig. 3, a transverse section on the line 3 3 of Fig. 1; Fig. 4, a detailed plan view of the pad, particularly illustrating the non-absorbing material between the two layers forming the opposite sides of the pad proper and the means by which such non-absorbing material serves for binding the edges of the inkabsorbing materials, and which may serve to secure the pad to the vertical rims of the receptacle from which is absent horizontal flanges; and Fig. 5 is a perspective view of r a pan-shaped inlcpad, illustrating the adaptability of my invention thereto.

Similar numerals of reference indicate the same parts in the several figuresjof the drawmg.

5 indicates the receptacle of a pad structure, which is shown to be of rectangular form, but maybe of any other form, consisting of a bottom 6, preferably of sheet metal,

and proj ecting at right angle thereto is a rim 7, pref- ,erably bent up from an extension of the metal piece forming the bottom, the two ends being provided with rims 8 8, which after being similarly bent up are provided with horizontal flanges 9 9, forming, so to speak, a groove at each end of the box for confining the ink-pad against displacement except at the farther and front side of the receptacle, which has no bent-up extension of the metal from the bottom, but has movably attached thereto a separate piece of metal bent to a V right-angular form, thereby providing a rim 10 and flange 11, hinged to the bottom of the receptacle by means of eyes 12 and 13, respectively, formed or otherwise secured to the opposing edges of the bottom and. the hinged piece or gate, the said eyesbeing connected by a rod 14.

The construction of the gate is preferably such that when it is swung from the opened position (shown in Fig. 1) to its closed operative position its flange will overlap both the pad and the end fianges 9 9 and fit both the flanges and the adjacent ends of the rims 7 7 of the receptacle as to be held against accidentally opening and substantially exclude air from access to the outer edge of the pad when not in use and from the receptacle when, as it preferably is, provided with a cover 15, hinged to the opposite side edge of the receptacle by means of opposing eyes and a pivot-rod in the same manner that the gate is hinged to the opposite side of the receptacle.

A cover or cap 15 is provided along-its side edge and end edges, respectively, with depending rims 16 and 17 17, which in the closed position of the cover projects below the top edges of the receptacle and against the outer sides thereof, including its gate and serving as additional means for holding the gate closed against accidentally opening.

Turning now to the ink-pad proper, 18 in dicates a plate of impervious material, preferably of sheet-tin or other suitable material, at the opposite sides and extending across the entire surface of which are coverings 19 and 20 of absorbent materialsuch, for example, as felt or other fabrics commonly employed for ink-pad purposes.

If desired or necessary for the purpose of either absorption or cushioning effect, or both, one or more pieces 21 and 22 of inkabsorbing material may be interposed between one or both of the coverings 19 and 20 and the several layers of materials, and how ever many there may be they are secured to the plate by cutting a number of slits 23 therein, and thereby forming tongues 24 and 25, which may be alternately bent in opposite directions, as indicated in Fig. 2, over upon the outer edges of the coverings 19 and 20, so as to clamp all of the layers firmly to the plate 18.

By securing the felt to the plate in the manner above described three important advantages accrueone that of easily, cheaply, and conveniently securing the absorbing materials against displacement and in a smoothed and outstretched condition and under tension, the other that of forming an edge to the pad, protecting it against disintegration, and, finally, that the tongues provide a means for securing the pad to a receptacle and against accidental detachment by bending two or more of them at intervals over the edge of a receptacle from which is absent one or more of the overhanging flanges 9 9.

In operation the ink-pad proper in its entirety after having been used upon one side until it is unfit for further use is withdrawn from its receptacle by first swinging the hinged rim of the receptacle to the position shown in Fig. 1, the pad being then withdrawn, reinserted in a reversed position, thereby presenting a fresh and unused surface, for it will be understood that by having an impervious plate of metal or other impervious material separating the opposing pads the ink from the worn-out side will not have penetrated, much more saturated, to the opposing unused side of the pad. After the pad is reinserted the hinged rim of the receptacle is closed, the fresh side of the pad is then properly inked and ready for use, and both side edges are isolated from contact with the fingers while in use and also when closing and opening the cap or covering, which is preferably used in connection their drying and hardening.

In conclusion, it should be observed that there is a further important advantage in having the intermediate felt of the pad sheet-tin or other impervious material or metal adapted to be bent upon itself, so as to clamp the edges of the absorbent materials thereto by means of a series of tongues, for such materials and the edges thereby formed from them prevent the possibility of the unavoidable swelling of the absorbent materials from overtightening the pad in its receptacle, while at the same time such edges provide for permanently maintaining such a fit between the edges of the pad proper and its receptacle that it may be maintained against shifting about and yet easily removed from the receptacle.

In Fig. 5 is illustrated a pan-shaped inkpadthat is to say, a receptacle provided with straight flanges and such as is usually employed in hand-stamps in which the type-plate has a rotary movement toward the ink-pad in making contact therewith, which pads are invariably non-detachable from the receptacle and in the majority of instances are shredded and Worn out long before the type-plate is, and are therefore necessarily thrown away at a substantial loss desirable to avoid, especially when the cost of a pad is very infinitesimal as compared with the rest of the structure. By my invention, however, it will be seen that not only a non-reversible, but a reversible, pad may be practically secured to such a jpan-shaped receptacle by bending some i of the tongues over the rim of the pan and removed by unbending and after reversing l the pad then retaining the same tongues, or others, if one or more of those originally bent are weakened or broken off.

I-Iaving described my invention, what I desire and claim to secure by Letters Patent is 1. An ink-pad structure comprising in combination a receptacle provided with a pad-retaining device comprising overhang- 1 ing flanges at one or more sides thereof, a

imovable rim at one side, and a reversible with all such pads to retard as far as possible pad adapted to be inserted in and confined from accidental detachment, but removable from said receptacle, substantially as described.

2. An ink-pad structure comprising in combination a receptacle provided With a pad-retaining device comprising overhanging flanges at one or more sides thereof, and a hinged rim at one side, and a reversible pad adapted to be inserted in and confined from accidental detachment, but removable from said receptacle, substantially as described.

3. An ink-pad structure comprising in combination a suitable receptacle, a pad removably held therein, said pad being provided with a centrally-located impervlous plate having tongues alternately bent over the pervious members of the pad and operating to protect the edges from Wear and the swelling of the pad from tightening its edges against the side of the receptacle, substantially as described.

In Witness whereof I have hereunto set my hand this 4th day of May, 1906.
